CAN-CLOSING MACHINE.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed April 26, 1911. Serial No. 623,513.

To all 1 711 it m ('j/ comm-n Be it known that we. JESSE E. Animals andIvan F. have, citizens of the United States, residing at Canonsbur inthe county of lVashington, State of Pennsylvania, and Syracuse, Onondagacounty, New York, respectively, have invented certain new and usefulImprovements in Can-Closing Machines, of which the following is adescription, reference being had to the accompanying drawing, and to theletters and figures of reference marked thereon.

The invention relates to new and useful improvements in an closingmachines, that is, machines for double-seaming an end or a cover onto afilled can.

An object of the invention is to provide means which may be manuallyoperated for placing the covers underneath the seaming head, and betweenthe rotary chuck and the can body.

A further object of the invention is to provide means for centering thecan cover underneath the seaming head and over the can body and forcentering the can body relatively to the seaming head, and round u thesame for the cover.

A still further ob 'ect of the invention is to provide means for placingcovers under the seaming head; centering the same relative to theseaming head and supporting said cover temporarily; centering a can bodyunderneath the cover and lowering the cover onto the can body andholding the same on the can body until secured thereto by the seamingroll. These and other objects obvious, and will in part more fullydescribed. a

In the drawings which show by way of will in part be be hereinafterillustration one embodiment of the inventhrough the cover feed,showingthe plunger for separating the cover from the stack; Fig. 5 is aside view of the parts shown in Fig. 3; Fig. (l is a sectional viewshowing a can body; acover supported above the same I and the seaminghead beforcbrought into engagement with the cover; Fig.7 isa similarview, showing the cover seated in the can body by the seating pad; Fig.8 is a similar view, showing the final operation of the seaming rolls;and Fig. 9 is a similar view showing the can closed and the partsreturned to normal position for discharging the cans.

frame 1 is provided on which is mounted a main shaft 2, which may bedriven in any desired way. A countershaft 3 is operated from the mainshaft through a belt councction 4. The seaming head 5 is carried by avertical shaft 6, which is mounted in bearings 7, 7, supported by theframe 1. The shaft 6 carrying the seaming head is rotated through thegear connection 8 with the countershaft. 3.

The seaming head includes an inner and outer sleeve 9 and 10, see Fig.6. Mounted on the sleeve 10 is a curling roll 11 and a flattening roll12, for performing the usual nccting a can end or cover to a can body bya rolled double seam. These seaming rolls are carried by levers 13,which are operated by cams on the sleeve 9, in the usual well knownmanner.

and the sleeveis free to chuck. Located centrally of the chuck andseaming head is a seating pad 15, which is carried by a stem 16extending upwardly through the shaft (5, which is hollow, and said stematits upper end carries acollar 17, which is connected to a lever 18operated from a cam on a cross shaft 19, which may be operated in anydesired way from the counter-shaft 3. The shaft 6 is moved up and downin order to bring the seaming head into contact. with the cover, andalso in order to bring the seaming rolls into contact with the edge ofthe cover by a crank lever" 20, which is operated through the arm 21which carries a roller running in a cam groove 22 in a disk on the shaft19.

Underneath the seaming head is a support 23, on which the filled cans tobe closed or to have covers attached thereto, may rest and move. Thissupport 23 is adjust ably carried by the frame 1., and may be moved upand down by a screw 24, so as to position the support for differentsized first and second seaming operations for con- A chuck 1-1 ismounted on the sleeve 10,

rotate about said bell In carrying out the invention, a suitable mossescarrying the seaming head, so as to move the plate out of the wa y oftheseaming rolls which are brought first one and then the other intocontact with the flange on the can cover and can body to form a doubleseam.

After the double seam is completed, the

seaming head will move upward and release the cam The plate 31 Wlll alsomove upward with the seaming head and the can cover which is nowsmallerin diameter than before it was attached to the can body, may movedownward through the opening 38 in the supporting plate 31, and theseaming head and centering device will thereby be entirely released fromthe can body, so that it may be ejected from the machine.

It will thus be seen that by the above mechanism, the can coversareearried by mechanical means underneath the seaming head and centeredrelative thereto. The covers are also temporarily supported until a canbody is brought underneath the cover. Furthermore, when the parts are inproper position and the seaming head descends to close the can, the canbody will be centered, the cover placed thereon and seated in the canbody,-and then the cover secured to the can body by a double seam.

It is obvious that minor changes in the details of construction may bemade without departing from the spirit of the invention as set forth inthe appended claims.
